Some people really need a lesson on how to close a door quietly. During the daytime I don't care, but at 5:00 am, come on people. If you want to get on the road that early fine, but please be respectful of your neighbors and at least TRY to close your doors quietly. I'm not talking just about a car/rig door, but the basement doors as well. Morning rant over now. Thank you.

It's the same deal with the tent campers staying up late around the campfire and getting that 'one last thing' out of the car at midnight. Just closing a car door normally can be heard throughout the campground. Folks who just camp once or twice a year tend to forget how sound carries when everyone else is quiet.

If that is your biggest problem you are doing OK. Kind of like living in a multi family apartment building and complaining you can hear other people. Or living near an airport and complaining about plane noise.
There are other people surrounding you in a campground. There will be some noise.
That doesn't mean slam the door intentionally,but I don't think you'll ever have absolute silence as long as there other people involved.

Guilty...once - Camped while traveling for one night. We were surrounded by partiers - throwing F words around, loud, obnoxious until 2-3:00 a.m.. We did not plan to leave early but wanted our children out of there. We got up at 4:30 - folded down Pop-up, talked loud, kept van running while finishing, & slammed everything we could. Normally when we leave early we whisper, close carefully, and don't start truck until we have to. Wasn't in the mood to be kind that day.
